IMPROVEMENT IN LAMPS.

To all whom, it may 00/006170:

Be it known thatl, ROBERT NELSON EAGLE, of the city and county ofWashington, in the District of Columbia, have invented a certain new anduseful Improvement in Lamps; and I do hereby declare the following to bea full and exact description of the same, reference being had to theaccompanying drawings, making part of this specification, in whichFigures 1 and 2 are vertical sections of lamps illustrating my inventionunder different modifications. Figs. 3 and 4 are perspective views ofholders or fastenings detached.

Similar letters of reference indicate corresponding parts in the severalviews.

The subject of my present invention is an improved device for connectinga feeding-wick with the burning-wick of common lamp in such a mannerthat the said burning-wick may be more fully used, produce a moreuniform flame, and be less influenced by variations in the quantity orheight of oil in the lamp-reservoir. My said improved device consists,essentially, of a detachable wick holder or fastening, which mayattached to the wick-tube in any suitable way, or, in some instances,may

I be entirely detached therefrom, and which will be adapted for theattachment of the feeding-wick, holding the side or end of the latter insuch close contact with the burningwick as to insure the conduction ofoil, while permitting the burning-wick to slide freely up or down.

In order that others skilled in the art to which myinvention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe its construction and operation.

A may represent the shell, B the wick tube,

0 the elevator, and D the wick, of a lamp of ordinary construction. Erepresents a wick holder or fastening, of metal, formed at c with a slotor series of holes for the secure attachment, by stitching, rivetin g,or other suitable means, of a feedingwick, F, sufficient length to reachthe bottom of the reservoir.

The wicks D and F are held in sufficiently close contact to insure freepassage of oil from one to the other. The wick D is free to slide up ordown, as moved by the elevator G, and

the wick F, being fixed, will elevate the oil with uniformity and supplyit constantly to the burning-wick D. It will thus appear that theworking of the lamp is not materially affected byvariations in thequantity of oil in the reservoir, as the wick F constantly reaches tothe bottom of the reservoir, and will elevate the oil so long as anyremains, and supply it to the burning-wick D. i It will further appearthat the wick D can be burned until its lower end passes entirely abovethe reach of the feeding-wick F, which cannot occur until the said lowerend of the burning-wick passes entirely within the wick-tube proper.

The'connection between the wick-holder E and the lamp-burner may beeffected by a plate or rod, I, Fig. 1, extending upward to any desiredheight inside or outside the wick tube, and passed through a slot orslot-s therein, or over the top, to hold it firmly.

The holder E may be prevented from passing up too high or moving ineither direction by its own dimensions, or by the aid of a projectin gclaw or catch, i, or any other suitable device. A second row of holesmay, if desired, be employed for the attachment of the wick, asrepresented at e.

In Figs. 2 and 4, 0 represents flanges projectin g either inward oroutward from the top of the wick-holder E and engaging withcorresponding flanges or projections upon the bottom of the wick tube orshell, so as to constitute a sliding attachment for the said wickholder.

(2 represents a slot for the reception of the end of the feeding-wick,and c a range of perforations to which it may be stitched for additionalsecurity.

By dividing the wick-holder, as shown at K, either at its edges orsides, or dispensing entirely with one side, an elastic clamp isproduced, which renders the introduction of the wick more easy, and willhold them closely in contact by pressure against the opposite side ofthe wick holder or tube, in which case ad ditional security will beafforded by the use of an inclosing-ring.

The wick'holder may be used without attachment to the wick-tube, or maybe loosely connected thereto by a link-hook, or any other suitablemeans, as illustrated at c in Fig. 3, c in Fig. 1 being a hook upon theburner or shell for the reception of such link or chain.

In using the wickholder the feeding-wick may be simply passed through oraround it,

or through a slot, 0 therein, and brought down and securcd togetherbelow.

If preferred, two feeding-wicks may be employed, one attached to eachside of the holder or fastening, so that the burning-wick may pass upand down between them. The advantages of this arrangement will be thatoil will be conducted somewhat more freely to the burningwick, and thelatter, by reason of its being subjected to equal friction from similarsurfaces on both sides, will be less liable to deflection in the act ofraising or lowering it. After the feeding-wick has been secured in placethe burning-Wick may be introduced from above in the usual way.

I am aware that permanent teeding-Wicks have before been applied tolamps in various Ways, and do not therefcre claim, broadly, a stationaryfeeding wick.

My fastening constitutes an article of manufacture, which, in itself,may be so complete as to admit of a feeding-wick being applied to anyordinary lamp with little or no alteration in its construction as Wellas to lamps manufactured with a view to its use.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is- I A fastening substantially asherein described, for securing one or more feeding-Wicks to a lamp.

In testimony of which I have hereunto set my hand this 18th day of June,1864:.

R. N. EAGLE.
